NAME

de — DEC DC21x4x Ethernet device driver

SYNOPSIS

To compile this driver into the kernel, place the following line in your
kernel configuration file:
devicede
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
if_de_load="YES"

DESCRIPTION

The de driver provides support for the Ethernet adapters based on the
Digital Equipment DC21x4x based self-contained Ethernet and Fast Ethernet
chips.
The de driver supports the following media types:
autoselect Enable autoselection of the media type and options
10baseT/UTP Set 10Mbps operation on the 10baseT port
10base2/BNC Set 10Mbps operation on the BNC port
10base5/AUI Set 10Mbps operation on the AUI port
100baseTX Set 100Mbps (Fast Ethernet) operation
100baseFX Set 100Mbps operation
100baseT4 Set 100Mbps operation (4-pair cat-3 cable)
The de driver supports the following media options:
full-duplex Set full duplex operation
Note that the media types available depend on the particular card in use.
Some cards are explicitly programmed to a particular media type by a
setup utility and are not changeable.
Use the ifconfig(8) command and in particular the -m flag to list the
supported media types for your particular card.
The old “ifconfig linkN” method of configuration is not supported.
